2007 - 2014 GM SUVs Diagnose & Repair P015B or P015D HO2S DTCs (Chevy Avalanche / Tahoe / Suburban)

[@davidaguilar3825]

Hello hopefull you can help me i got a 2014 tahoe with both p015D and P015B error codes on. So im wondering are both these codes on because i put acetone in fuel tank it was recommended by a friend to do so beacuse i had told him it felt like cats are plugged...im kinda lost and do know what to do can you help

There is a reason acetone is sold in the paint aisle, not the automotive aisle of the store. It is one of the chemicals specifically called out to *NOT* be added into fuel by General Motors - static.nhtsa.gov/odi/tsbs/2013/SB-10068973-5448.pdf Whether that specifically caused the DTCs you have, or is a coincidence, would be impossible to determine and could only be confirmed by swapping in a known good OEM O2 sensor into either bank as a test.

Parts cannon, gotta love it.

[@DrShock]

Yeah, cannons are usually only accurate to within 10%, at around 5% of the time. Better to run thru the service manual diag tree and be sure the vehicle does not come back than firing one.

Guilty as charged. LoL But I usually get lucky and hit on the first shot.

Where and how do you get your factory service manuals?

There's a link in the video description for where to search for used hard copy manuals, especially when they are out of print. You can also pay a subscription fee to ACDelco to get online access at www.acdelcotds.com.
